Description
Technical field
The present invention relates to a kind of wireless signal transceiver, the ID identity device that specifically a kind of employing wireless signal identifies object and the identification method of this ID identity device, the using method of this ID identity device.
Background technology
In the life, people always wish to obtain Useful Information in the shortest time, for example at the supermarket in, people wish to obtain the information relevant with oneself required commodities purchased and the concrete deposit position of these commodity in the shortest time.Therefore, the part supermarket uses the ID identity device to identify each object, promptly identifies each commodity of super incity, and the multimedia player with reader is installed on the shopping cart that client uses.This ID identity device be placed on respectively extensive stock near, each ID identity device has a microprocessor, store the ID identification code of its lay down location commodity in the storer of microprocessor, also have a radio frequency transceiving module in the ID identity device, send the radio frequency signal that comprises these commodity ID identification code to reader.After reader receives radio frequency signal, according to the power (ESS OR RSS) of receiving radio frequency signal, can discern on the one hand and the ID identity device between distance, can obtain the ID identification code of these commodity on the other hand, multimedia player will be play the relevant information of these commodity according to this ID identification code, comprise title, the place of production, quality of commodity etc., and client can understand commodity by these information, need to determine whether to buy, greatly facilitate client's free choice of goods.
But, because radio frequency signal has the emission characteristics of diversity, directionality is relatively poor, cause the reader that is in a certain position can receive a plurality of ID identification codes simultaneously, the merchandise news that multimedia player is play is the most close client's merchandise news not necessarily, in addition, restraining mass is being arranged, human body moves, even under the interference of weather condition, and reader antenna and ID identity device antenna effect angle is different, the capital makes the power of radio frequency signal bring interference, therefore, when the spacing of object hour, can't judge accurately that according to the power of radiofrequency signal reader is nearest from which object, choose to client and bring certain influence.The more important thing is,,, so consume a large amount of electric energy, be unfavorable for the saving of the energy even also send radio frequency signal during non-business in the supermarket because the ID identity device is in running order for a long time.
Summary of the invention
Fundamental purpose of the present invention provides a kind of power consumption less I D identity device;
Another object of the present invention provides the ID identity device of clear each object of sign of a kind of energy;
A further object of the present invention provides a kind of ID identification method of using above-mentioned ID identity device;
Another purpose of the present invention provides a kind of using method of above-mentioned ID identity device.
For realizing above-mentioned fundamental purpose, ID identity device provided by the invention includes microprocessor, this microprocessor has microprocessing unit, and microprocessor stores has the environmental light brightness threshold value, the ID identity device also is provided with by the power unit of power processor to microprocessor power supply, the wireless signal delivery unit that is connected with microprocessor, in addition, also be provided with the environmental light brightness detection module that detects the surrounding environment luminance brightness, this environmental light brightness detection module is connected with microprocessor, when the environmental light brightness detection module detected environmental light brightness and is lower than the environmental light brightness threshold value, microcontroller carried out park mode.
By above scheme as seen, in non operation time, environmental light brightness is lower in the supermarket, and the environmental light brightness detection module detects the surrounding environment luminance brightness when low, can make the microprocessing unit of microprocessor enter the dormancy program.Because the electric energy that the electric energy that microprocessing unit enters the dormancy program consumes consumes under the normal operating conditions, therefore, will significantly reduce according to the electric energy of the ID identity device consumption of such scheme, help the saving of electric energy.
A preferred scheme is, adopts a radio frequency transceiving module in the wireless signal delivery unit at least, is used to launch the ID identification code of object and receives more new data.Because the radio frequency signal radiation scope is wider, use the ID identification code of radio frequency signal emission object, can guarantee that reader near receiving corresponding ID identification code after the ID identity device, shortens the time that reader receives the ID identification code.

For realizing an above-mentioned purpose again, the ID identification method of ID recognition device provided by the invention comprises that the storer to microprocessor writes the environmental light brightness threshold value, microprocessor detects power unit and whether is in low-voltage state, and in this way, microprocessing unit enters the dormancy program; Otherwise,, judge that environmental light brightness whether greater than the environmental light brightness threshold value, in this way, enters normal operating conditions by environmental light brightness detection module testing environment luminance brightness situation; Otherwise, microprocessing unit enters the dormancy program, wherein, comprise in the dormancy program that microprocessing unit enters the low frequency operation pattern, sets the dormancy time of doze output then, enter park mode again, and after waking up, judge whether power unit still is in low-voltage state, and in this way, microprocessing unit enters unlimited park mode, otherwise, by environmental light brightness detection module testing environment luminance brightness actual value.
To detect surrounding environment by the environmental light brightness detection module after the work of ID identity device, and when environmental light brightness was lower than threshold value, microprocessing unit entered park mode.Like this, the ID identity device consumes less electric energy when environmental light brightness is low around, thereby reduces the consumption of electric energy.
Further scheme is, can the infrared detection module that be connected with microprocessor be set in the ID identity device, is used to detect infrared signal.After microprocessing unit enters normal operating conditions, judge whether the infrared detection module receives infrared signal, in this way, the wireless signal that wireless signal delivery unit emitting times in the unit interval is more, otherwise, the wireless signal that wireless signal delivery unit emitting times in the unit interval is less.This identification schemes is further energy-conservation on the one hand, can prevent that on the other hand the reader that passes the wireless signal district fast from missing wireless signal.
For realizing above-mentioned another purpose, the using method of ID recognition device provided by the invention is in the bigger occasion of object spacing, each object is nearby placed one or more ID identity device respectively, and the radio frequency signal of launching with ID identity device wireless radio frequency modules identifies each object.Certainly, this object can be each sub regions in the specific region, subregion big place a plurality of ID identity device, what subregion was little then can only place one, what concrete quantity depended on ID identity device wireless signal involves scope and the strong and weak discernible scope of radiofrequency signal, guarantees that reader enters the ID identification code that can correctly discern this subregion behind a certain subregion.
If the object spacing hour, can use the ID identity device that only is provided with the infrared module to identify each object, during use the ID identity device is placed on each object near, behind the infrared detection module receiving infrared-ray signal of ID identity device, send interrupt request to microcontroller, the infrared signal that uses the ID identity device to send identifies each object.Certainly, object also can be the object that is placed in the subregion.Because the good characteristics of directionality that infrared signal has, can guarantee that reader can accurately receive each ID identity device and send infrared signal, accurately each object is identified, make full use of the good advantage of infrared ray directionality, the ID identity device can accurately identify extensive stock.And can save the cost of ID identity device greatly, this is that the cost of radio frequency transceiving module is higher because the cost of infrared module is lower.
Certainly, if need the more and spacing of the object quantity of sign hour, the available ID identity device that is provided with infrared module and radio frequency transceiving module be placed on respectively each object near, behind the infrared detection module receiving infrared-ray signal of ID identity device, send interrupt request to microcontroller, use radio frequency signal that the ID identity device sends earlier and after the infrared signal that sends and identify each object.

The ID identity device that it is emphasized that present embodiment is provided with infrared detection module 3, infrared module 6 and radio frequency transceiving module 8 simultaneously.For other embodiment, these modules all can be configured selectively, promptly can only use infrared module 6, and do not make radio frequency transceiving module 8, perhaps only use radio frequency transceiving module 8 and do not use infrared module 6, perhaps the both uses, in addition, infrared detection module 3 is can be obsolete in these embodiments, and this does not influence enforcement of the present invention.
Therefore, can define three types card according to the apolegamy situation of infrared module and radio frequency transceiving module, the embodiment that three kinds of ID identity device promptly can be arranged to establishing the ID identity device of infrared transmission module and radio frequency transceiving module simultaneously, is defined as A11 type card; The ID identity device of radio frequency transceiving module is not set only being provided with infrared transmission module, is defined as A10 type card; The ID identity device of infrared transmission module is not set only being provided with radio frequency transceiving module, is defined as A01 type card.Can be according to actual conditions, select in three kinds of cards one or more that particular commodity or zone are identified, the sign that the zone is carried out more specifically can be that the number order that needs after reader enters to carry out identifies, and for example controls the volume control command of the player of having reader etc.
Referring to Fig. 3, if in the specific region, the spacing of the object that need be identified is bigger, can not cause interactional distance between the radio frequency signal of promptly a plurality of ID recognition device emissions, can use A01 type card sign that each object is identified respectively.Each specific region such as cashier overhung A01 type card 11 in the supermarket, be used for identifying each different cashier, preferably place the A01 type card 11 more than 3 or 3, and be distributed in the boundary of this specific region, make reader can correctly discern residing zone, after the reader of shopping cart enters the cashier zone, can receive the radio frequency signal that A01 type card 11 sends, can also discern the power (ESS OR RSS) of this radio frequency signal, promptly according to receiving that the strong and weak degree of radiofrequency signal differentiates residing zone.In a specific region, use a plurality of ID identity device, can reach the purpose that radio frequency signal covers whole cashier zone (this specific region), certainly, the ID identification code represented of the radio frequency signal of the emission of a plurality of ID identity device in the cashier zone should be identical.
Referring to Fig. 4, if in the specific region, need the object that identified less, preferably, the quantity of object is below 256, be convenient to the ID identity device and use each object of binary coding representation ID of less figure place, and the spacing of each object is less, may cause interactional distance between the radio frequency signal of promptly a plurality of ID recognition device emissions, then can use A10 type card to identify each object respectively.At the one or more A10 type of the overhung card 12 of every kind of object of shelf in supermarket, and guarantee that every kind of object all has unique ID identification code correspondence.Before shopping cart rests in this kind of shelf commodity, can receive the infrared signal that A10 type card 12 sends, accurately receive the ID identification code of this commodity correspondence, multimedia player is just play the relevant information of these commodity.Equally, if the commodity of same kind are more, when distributed more widely, the infrared signal that also can use a plurality of ID identity device to send identifies with a kind of commodity.
If in the specific region, need the object kind that identified more, preferably, quantity is more than 256, and spacing is less, be to cause interactional distance between the radio frequency signal of a plurality of ID recognition devices emission, can use the A11 type to stick into line identifier.A11 type card earlier sends the ID identification code of a certain object by wireless radio frequency modules in the radio frequency signal mode, and at once by infrared module emission infrared signal, this infrared signal can be an ID identification code of not representing the ID of object again.For example, in big-and-middle-sized supermarket, the commodity shelf are bigger, the gap ratio comparatively dense and the quantity of shelf are more, the ID identification code of each shelf is encoded with regard to needing more binary digit, at this moment, use A11 type card just shorter, can save the electric energy of A11 type calorie consumption with the scramble time that the radio frequency signal mode sends the ID identification code.In addition, because the directionality of radio frequency signal is relatively poor, reader can be received the ID identification code that a plurality of A11 type cards send with wireless radio frequency mode within a short period of time.Therefore, A11 type card with ID identification code of wireless radio frequency mode emission after, launch infrared signal at once, like this, reader is judged the ID identification code that and then receives infrared signal after the ID identification code that receives the wireless radio frequency mode emission again, be only the ID identification code of shelf of living in, and drive the relevant information that multimedia player is play corresponding goods.Reader does not receive infrared signal after receiving the ID identification code of wireless radio frequency mode emission, the shelf of representing this ID identification code correspondence are not the shelf of close reader, and multimedia player is not play the relevant information of these commodity.
Certainly, if need more its spacing of object of being identified hour in the specific region, also can use the method for A01 type card and the dual use of A10 type card to identify.For example, as shown in Figure 5, the supermarket is divided into a plurality of subregion U1, U2, U3, and the radio frequency signal that uses A01 type card 11 to send identifies each sub regions.Simultaneously, a plurality of A10 type of the shelf overhung card 12 in each subregion, the infrared signal that uses A10 type card 12 to send identifies multiple different commodity in this subregion.Like this, when reader enters a certain subregion, as enter subregion U1, can receive the radio frequency signal that A01 type card sends and identify this subregion, and the time near a certain commodity, receive the infrared signal that A10 type card sends, reader can obtain the ID identification code of this subregion and commodity, thereby drives the relevant information that multimedia player is play these commodity.
In the present embodiment, the ID identity device is the top that is suspended on subregion or commodity, the infrared signal of ID identity device emission is directive ground vertically, reader can receive the ID identity device more accurately and receive single infrared signal like this, the infrared signal phase mutual interference of effectively avoiding different I D identity device to send.Certainly, if the ID identity device is positioned on the shelf or other place does not nearby influence enforcement of the present invention yet.
Below, the principle of work of ID identity device is described in conjunction with Fig. 6 to Fig. 9.Referring to Fig. 6, Fig. 6 is the process flow diagram of ID identification method embodiment of the present invention.The ID identity device need write information and necessary programs such as environmental light brightness threshold value before using in the storer of ID identity device, guarantee that the ID identity device can operate as normal.Execution in step S1 after the ID identity device is started working starts microprocessing unit and all circuit of microprocessor, and finishes the guiding of required software and the initialization of interior each assembly of elements of microprocessor.
Among the step S2, microprocessing unit detects the voltage of power unit by power-supply controller of electric, judges whether power unit is in low-voltage state, execution in step S4 then in this way, and microprocessing unit enters the dormancy program.If power unit voltage is normal, detect surrounding environment luminance brightness situation by the environmental light brightness detection module, and with the environmental light brightness threshold comparison in detected environmental light brightness actual value and the storer, judge that whether actual value is greater than threshold value, be execution in step S3, execution in step S5 then in this way, microprocessing unit enters normal operating conditions, otherwise execution in step S4, microprocessing unit enter the dormancy program.
Referring to Fig. 7, Fig. 7 is the process flow diagram after microprocessing unit enters the dormancy program.After microprocessing unit enters the dormancy program, at first, be operated in low frequency mode, set the dormancy time of doze output then, be i.e. execution in step S12 execution in step S11.Dormancy time can be 30 seconds to 120 seconds, and in dormancy time, microprocessing unit execution in step S13 enters park mode.Park mode can be the park mode that microprocessing unit carries, and also can be the park mode of realizing by programming, and microprocessing unit consumed power under park mode is far smaller than the electric energy that consumes under the operate as normal.
After dormancy time arrives, microprocessing unit will be waken up, and execution in step S14, judge once more whether power unit still is in low-voltage state, execution in step S15 in this way, and microprocessing unit enters unlimited park mode, wakes up until changing power unit and restarting.If it is normal that power unit voltage recovers, execution in step S16 then, testing environment luminance brightness situation once more, if environmental light brightness greater than threshold value, execution in step S17, microprocessing unit enters normal operating conditions, otherwise returns execution in step S11.
This shows that microprocessing unit detects power unit and is in voltage status or detects the surrounding environment luminance brightness when being lower than threshold value, all enters the dormancy program, reduces the consumption of ID identity device electric energy.Especially the supermarket is in non operation time, and the ID identity device will be in unlimited park mode, will significantly reduce power consumption, helps energy savings.
Microprocessing unit normal operating conditions process flow diagram as shown in Figure 8.After microprocessing unit entered normal operating conditions, at first execution in step S21 was operated under the normal frequency pattern, and the initial value of online programming timer is set, this value can be 5 seconds to 10 seconds, i.e. execution in step S22, microprocessing unit can be during this period of time new data more.
Then, microprocessing unit execution in step S23, judge whether the ID identity device has radio frequency transceiving module, judge that promptly the ID identity device is the card of what type, if have radio frequency transceiving module, be A11 type card or A01 type card, execution in step S24 then, enter the less radio-frequency receiving mode, and execution in step S25, judge whether to receive radio frequency signal, if receive radio frequency signal, the expression staff upgrades the data of ID identity device, and then execution in step S26 enters the online programming pattern.If do not receive radio frequency signal, execution in step S27 judges whether the online programming timer is 0, execution in step S31 in this way, otherwise return execution in step S25.
Among the step S23, microprocessing unit judges that the ID identity device does not have radio frequency transceiving module, is A10 type card, execution in step S28 then, judge whether to receive infrared signal, if receive infrared signal, execution in step S29 then, enter the online programming pattern, if do not receive infrared signal, then execution in step S30 judges whether the online programming timer is 0, execution in step S31 then in this way, otherwise return execution in step S28.
By above-mentioned steps as can be known, after microprocessing unit enters normal operating conditions, at first detect whether receive radio frequency signal or infrared signal, if receive these signals then carry out online programming, i.e. new data more, if do not receive these signals, execution in step S31 then.
Among the step S31, microprocessing unit is the quick emitting times of zero clearing ID identification code, and the dormancy time of doze output is set, and microprocessing unit is execution in step S32 just, enters the dormancy program.After microprocessing unit woke up, execution in step S33 judged whether power unit is in low-voltage state, execution in step S39 then in this way, and microprocessing unit enters the dormancy program once more.If power unit voltage is normal, microprocessing unit execution in step S34 detects surrounding environment luminance brightness situation by the environmental light brightness detection module, if the supermarket is in non operation time, environmental light brightness is lower than threshold value, and microprocessing unit execution in step S39 enters the dormancy program.If environmental light brightness is greater than threshold value, execution in step S35, further judge whether the ID identity device is connected with outer computer or programmable device, if connection is arranged, expression ID identity device is just by the data transfer interface data download, execution in step S36 then downloads to the data such as ID identification code of program, renewal in the storer.If is not connected with outer computer, programmable device, execution in step S37 then, the ID identity device is launched the ID identification code that is stored in the storer.
During ID identity device emission ID identification code, to judge that the ID identity device is the card of which kind, if A10 type card, then the ID identification code is launched with infrared method, if A01 type card then launches the ID identification code with wireless radio frequency mode, if A11 type card, then the ID identification code is sent earlier with wireless radio frequency mode, again with infrared mode to send the ID identification code.
After the ID identity device emission ID identification code, execution in step S38, detect and whether receive infrared signal, if receive infrared signal, expression has reader close, and the ID identification code that infrared module and wireless radio frequency modules emitting times in the unit interval is more is not if receive infrared signal, then emitting times less I D identification code in the unit interval can reduce the electric energy that the ID identity device consumes like this.Microprocessing unit is finished and returns execution in step S32 behind the step S38.
By above-mentioned steps as seen, microprocessing unit is after renewal finishes data, to enter the dormancy program, and waking back judgement power unit voltage condition and surrounding environment luminance brightness situation up, just launch the ID identification code when having only normal its surrounding environment luminance brightness of power unit voltage, to save power consumption greater than threshold value.
Below in conjunction with Fig. 9 workflow after microprocessing unit enters the online programming pattern is described.Microprocessing unit enters the online programming pattern, judge at first whether the ID identification code that receives is the ID identification code that is fit to form, be execution in step S41, if form is fit to, execution in step S42 then, the ID identification code that receives is stored in the address of storer appointment, and with the zero clearing of online programming timer, i.e. execution in step S43.If the form of the ID identification code that receives is not suitable for, then directly return, the ID identification code that receives is not stored in the storer.
By the workflow of the structure of above-mentioned ID identity device and ID identity device as can be known, the microprocessing unit of microprocessor enters the dormancy program when environmental light brightness is lower than threshold value around, just the ID recognition device can help saves energy at the less electric energy of supermarket non operation time internal consumption.
And the ID identity device uses the infrared module with infrared mode the ID identification code to be launched, and makes reader according to the relevant information that clearly receives corresponding goods, effectively avoids reader to receive the generation of a plurality of commodity ID identification code situations simultaneously.
Certainly, the ID identity device is not limited to be applied in sign extensive stock in the supermarket, can also use as places such as conference and exhibition center, museums at other.For example, can place it in each sight spot of tourist district, the employing wireless radio frequency signal is emitted to the information of each sight spot ID identification code on visitor's the reader, and is introduced the relevant information at each sight spot to the visitor by reader.
Simultaneously, when the ID identification code of using radio frequency signal to carry identifies a plurality of subregion, can place one or more ID identity device, guarantee that reader can clear reception radio frequency signal according to the area situation of subregion.Equally, when using infrared signal sign object, if same object is distributed more widely, the infrared signal that also can use a plurality of ID identity device to send identifies.
At last; it is emphasized that; the invention is not restricted to above-mentioned embodiment, also should be included in protection scope of the present invention such as the change of sequence of steps in the change of radio frequency transceiving module building block, the ID identification method, the subtle change such as change of ID identity device placement location.In addition, an aspect of the present invention's design is to utilize infrared ray to have direction-sense characteristics, in the occasion that the object distance is less each object is used infrared signal sign object, obviously, also can adopt laser emitting module emission laser signal that object is identified, and with the laser detection module laser from reader is detected, to substitute infrared module and infrared detection module, this is the be equal to replacement relevant with technical solution of the present invention.
